Electromagnetic modelling of Leaf Water Potential under Ultra-Wide Band Microwaves Sensing

Abstract

Noninvasive sensor of plant that measure leaf concentration water is purposed. It is based on a microstrip structure where the loaded layer is represented by a mathematical model. The leaf is represented with the cellulose Cole-Debye model, that includes fresh water molecules which are simulated with different size to characterize the turgescence and plasmolysis behavior. The concept is validated and compared to Cole-Debye model for different situation of stress leaf, represented by an equivalent dielectric cell over the sensor
